She has 2 x 100g pouches normally per day, but this has gone up to 3
No dried food. With water available in two locations.
Her coat has become thicker, and she is definitely putting on weight.

Polyphagia (increased hunger) at Toots's age is usually associated with either diabetes mellitus or hyperthyroidism. The great majority of diabetics increase their water intake and urine output while just 35% of hyperthyroid cats do so. In either case, I expect weight loss instead of gain but I do see ~10% of hyperthyroid cats gain instead of lose weight. Toots's vet will want to perform a thorough physical exam including diagnostics in the form of blood and urine tests. A simple blood glucose should identify diabetes while a T4 and fT4 (total thyroid and free thyroid blood test) should identify hyperthyroidism.
